I want to make my Almirian Crusader Set look spiffy, but from the current accessories, there really aren't any that I would put on the set. Sooooo.... I'd like to suggest 2 ideas that I hope get accepted.
1. Horns - Horns can obviously be a helmet top accessory. There could be a variety of them, short horns, long horns, straight horns, curved horns, etc. etc. Or, they could simply be horns like the Dread Skelly ones. http://media.spiralknights.com/wiki-images/7/7a/Dread_Skelly_Mask-Equipp...
2. Wristbands - I know that these kind of accessories don't exist, but maybe OOO can create accessories for arms and legs. If this were to happen, then maybe wrist bands could be implemented as an arm accessory. My ideal wristbands would be spiked ones like Bowsers from Super Mario http://www.mariowiki.com/images/thumb/1/1f/BrawlBowser.jpg/200px-BrawlBo.... There could be a variety of accessories for arms and legs, like holsters or arm/leg guards.
These are my ideas. I know the 2nd one is a bit biased, but I hope that at least the first idea makes it into the game.
